SIDE AND CORNER FOR BUILDINGS.

Application filed May 23, 1918. Serial No. 236,162.

To all whom iii-may concern:

' Be it known that I, JopN K. SHAV,R

citizen of the United States, residing, at.

Minneapolis, in the county of Hennepin and State of Minnesota, haveinvented certain new and useful Improvements in Side Valls and Cornersfor Buildings; and I do hereby V declare the following to be a full,clear,'and exact description of the invention, such as will enableothers skilled in the art to which -Referring to the accompanyingdrawingsforming a part of this specification in which like numeralsdesignate like parts in all'the vie\vs Figure l is an elevational viewof a corner of the building treated in accordance with this invention;

Fig. 2 is a sectional View on the line 22 of Fig. 3, looking in thedirection of the arrows;

Fig. 3 is a sectional view on the line 33 5 of Fig. 2, ldoking in thedirection of the .arrows; and- Fig. 4 is an elevational View of themetal corner clip employed in this invention.

1, 2 and '3 indicate the upright timbers constituting the main cornersupports of a building, 4 and 5 indicate the usual wooden side wallmaterial employed in such buildings and 6 and 7 indicate sla'bs orboards made of.the material well known on the market as' insulite. This.insulite material is a paper board material ma-de of fibers obtainedfrom wood but it differs from the ordinary paper board in that it isexceed- .eingly light and is possessed of an unusual high heatinsulating Quality. That is to say, it resembles cork in many of itsphysical qualities it having a specific gravity of say not more than .3or .4 and it often-has a specific gravity as low as .2 or lower.

It is made of at least three different classes of fibers. The one classisso coarse that they really constitute slivers in that they are sayoften one eighth of an inch wide, and one half to one inch in length.The second class of fibers are more or less string like in that they aresay from one thirty second of an inch to one sixty fourth of an'inchwide, and are from one half to one inch, or two inches long.

Thethird class of fibers are more or less hairlike inthat they are fromsay one hundredth to one two hundredth of an inchin diameter and are/sayfrom one half inch or less in length.

. In addition to these various classes of fibers, the mass is mixed witha considerable quantity of ordinary sulfite fibers employed in papermaking. The result of felting together'into a homogeneous mass fibershaving such great variations in their coarseness is to make a bodyhaving great porosity. high heat insulatingqualities, and'gone Welladapted for the outer covering of buildings. On the-other hand, theextreme edges of the boardsor slabs made from this material are more orless fragile, and therefore,'it is desirable to protect them from theweather and from rough usage.

Owing to this fragility and to the unusually porous nature of thematerial said edges, unless special precautions are taken, are unsuitedforbeing-fastened, like other boards. on the sides of houses; andfurther, even when fastened in place they will rapidly deteriorate underthe weather, unless precautions are taken to protect them.

Accordingly, thedooards .of insulite such as 6 and Tare laid'ov er eachother as illus-.

trated in Figs. land 3, and their extreme meeting edges such as 8are'covered by a .metal piece indicatedas at 9. This metal piece isconveniently struck up by any suitable dies, it is provided with faces10 and 11 at substantially right angles to each other,

mvith projections. as best shown in-Fig. 4.

in order to facilitate the biting in of the pieces 9 as will be clearfrom the drawings.

The strips or members 9 are of a length equal to the width of theinsulite boards,

influence of the their serrations on tlieir lips 12 and 13 extend thewhole length of said strips, andat one end the sides of said strips arebent inward to form the additional pairs of lips 11. These said lips 11are coextensive with the sides 10 and 11 as shown, and are thereforedisposed at right angles to each other as will be clear from Figs 1 and4. They extend underneath and protect the bottom edges 16 of theinsulite boards 6 and? as will be clear from said drawings. I

It will, therefore, be observed that the members 12 and 13 bite into andsecure a firm hold on the porous body of the insulite, that the two,walls 9 and 10 disposed at right angles to each other, effectuallyinclose and protect from the weather the rough and freshly cut porousand'fragile edges of said insulite, and that the underlying members 14still further protect and secure the extreme side edges of said insuliteboards 6. The entire structure results in a joint which has shown itselfto be efiicient and satisfactory in practice.

Since the boards 5, for example, .overlap I each other asbestillustrated in Fig. 3,

there are left triangular spaces between said boards 6, and the innersidewall material 4. In order to close up all cracks or spaces of thiskind, I preferably employ the. wedge shaped pieces 17 which may be madeof wood, of insulite 'or of other material,

but of course, these spaces maybe left open" if it is so desired, I

After the construction above disclosed has beenprovided the partsare'firmly nailed together or otherwise secured in any suit- ;ablemanner. 'On the interior of the build ing. I provide when, desired,additional slabs j or boaijds of insulite-n' a-terial indicated at 19and 20, the extreme edges of which fit in between the edges of themembers 1 and3 whichare offset for this purpose as best disclosed inFig. 2. After the slabs 19 and 20 have been thus placed, any convenientplastic material, such as plaster 21 may be applied directly to theinsulite and thus the house is effectually sealed with an airspace 22between its inner and outer walls.

It is obvious that those skilled in the art may vary the details ofconstruction, as well as the arrangement of parts without departmg fromthe spirit of the invention, and therefore, I do not wish to be limitedto the above disclosure except as may berequired by theclaim.v

' \[Vh'at I claim is In a building the combination of corner supports; aside wall joined to said supports; a second side wall joined to saidsupports and making an angle with said first named side wall; a set ofoverlapping porous insulite'boards having fragile edges JOHN SHAW.
